Window cling



FIG. 1 is a perspective view of a window cling, showing my new design;

FIG. 2 is a front elevational view of FIG. 1, the rear elevational view being a mirror image thereof; and,

FIG. 3 is a left-side elevational view of FIG. 1, the right-side elevational view being a mirror image thereof.

The broken lines showing alternate reticile markings in FIGS. 1 and 2 depict environmental matter and form no part of the claimed design. 

CLAIM I claim the ornamental design for a window cling, as shown and described.
